Abstract

Equipment for the emission and distribution of light by optical fibres, particularly for in-line spectrophotometric control with the aid of a double beam spectrophotometer, namely one channel for the reference and one channel for the measurement. It has at least one complementary light source emitting through a system of optical fibres permanently towards a reference cell and sequentially towards one of the n measuring cells corresponding to the controls to be performed, the light information from the reference cell on the one hand and sequentially from each of the n measuring cells on the other being passed by the system of optical fibres respectively to the reference channel and to the measuring channel of the spectrophotometer.
